Vitamins & Minerals: Ascorbic Acid

Ascorbic acid is the pure, crystalline form of vitamin C, an essential nutrient for human health. It is typically manufactured through a chemical process, often starting with glucose derived from corn or other plant sources. It is also found naturally in many fruits and vegetables.

Manufacturers add ascorbic acid to foods primarily as an antioxidant to prevent spoilage and maintain color, especially in processed fruits and vegetables, meats, and beverages. It also functions as an acidulant to provide tartness and can be used as a nutrient supplement.

Ascorbic acid is widely recognized as vitamin C and is considered essential for immune function and collagen production. The U.S. Food and Drug Administration (FDA) lists ascorbic acid as Generally Recognized As Safe (GRAS) for use in food. International bodies like JECFA and EFSA have evaluated ascorbic acid. While high doses can sometimes cause digestive upset in sensitive individuals, it is generally considered safe at levels found in food.
